On average,bacterias are about I micrometre long. 有些細菌對人類是益的，但更多的是有害的。

In this case, the landfill leachates can be purified effectively by the method of Sublime Micrometre Filtration(SMF). 應用亞濾技術作深度處理，可有效地去除剩余的污染物質(zhì)，使出水達標。

The team's explanation is that the outer ring is made of very fine water ice particles, mostly less than a tenth of a micrometre across. 該小組解釋說,光環(huán)外圈由無數(shù)水冰碎屑組成,大部分水冰屑僅為十分之一毫米大小。

The particles may be metal or metal compounds, and are often smaller than one micrometre ( one fiftieths the width of a human hair). 這些微粒可以是金屬也可以是金屬化合物，通常比一微米還小（頭發(fā)絲的1/50）。
